Explain how one can rate the closeness of related organisms by comparing dna base sequences

Harman [31]3 years ago

Scientists believe we all originated from one common ancestor. using our dna base sequences, we can determine how closely related organisms by looking at when the first differing sequence occurs. for example, U U T A you can determine that
U U T T 1 and 2 are more
U U A T closely related than 1 and 3 because their dna sequence stays the same for longer. hope this helps :)

What properties of carbon explain its ability to form different large and complex structures
Butoxors [25]
A carbon structure is visually a highly disordered structure.

It is for this reason that it lacks structural integrity .

A carbon structure forms at the edges or is the residue of other elemental compounds.

The disorder of this structure allows it to have many available bonds and and is responsible for building more complex carbon based molecules.

The structural organization of autonomic nervous system or ANS is different from somatic nervous system or SNS.

In the ANS,  the motor neurons of the central nervous system do not directly control visceral effectors. They synapse with visceral motor neurons  or  preganglionic neurons in ganglia, and the ganglionic neurons control the visceral effectors.
